Attackers can pass a roughly 268435460-byte packet through the libavcodec API, overflowing the bit count so decode_frame() reads from a NULL buffer and causes denial of service.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":5.7,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":4.7,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794258419307,"publishedAt":1794251450150,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25704"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/FFmpeg/FFmpeg/commit/839c93f261cd3e1719edfac4244a2d0055ce8841"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/jvdec.c#L169"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://github.com/FFmpeg/FFmpeg"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-null-pointer-dereference-in-jv-video-decoder"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
